Bug 22534 – ImportC: const pointer (not pointer to const) is treated as transitive const

A system header on macOS (<sys/_types/_fd_def.h>) actually has an inline function with a const pointer (not pointer to const). This header is transitively included by Python.h. The actual header has a lot of macro expanded junk, but it boils down to a function that looks like this: // constp.c struct S { int x; }; inline void setit(int i, struct S *const p){ p->x = i; // constp.c(6): Error: cannot modify `const` expression `(*p).x` }

Hmm. The solution could be to simply ignore a top level const when it's a pointer.
